She won Best Actress, and that adorable, self-deprecating moment embodied what she'd become: America's hilarious, awkward, relatable sweetheart. Sunday, she's up for Best Supporting Actress, but a win might not play so well.

Let's also recall last year's Best Supporting Actress winner — Anne Hathaway. Months of backlash preceded — and when she won, the headlines were about how she'd picked an ugly dress and annoyed with her speech — not her acting accomplishment.

Hathaway was once beloved with hit movies like "The Princess Diaries" and "The Devil Wears Prada." The tide turned.

A win Sunday — another Oscar, and so soon — might make things even worse. Would another endearing speech on the entertainment industry's biggest stage, in front of millions, be the tipping point?

Already, in December, Vulture published a piece accusing the actress of faking her realness: "Lawrence gives off the vibe of a woman annoyed by the endless repetition of a press tour, but she exploits it to perpetuate her status as a movie star that is nonetheless 'real.'"

And Salon sliced at her Internet popularity, "... a GIF, like the ones of Jennifer Lawrence adorably tripping or goofing off, iterates endlessly; eventually one wants to close the window."

There may be nowhere to go from here but down.

Truly, a loss Sunday might be the perfect exit Lawrence is looking for.

Remember — even with a break from acting, Lawrence has two more "Hunger Games" movies coming out over the next two years. That means press tours, premieres — she'll still be in the spotlight.
